[0001] The present application claims priority to the prior application with the patent application No. 202111301406.X titled "LURASIDONE HYDROCHLORIDE ORAL SOLUBLE FILM COMPOSITION, PREPARATION METHOD THEREFOR AND USE THEREOF" filed to the China National Intellectual Property Administration on November 4, 2021, the contents of which is incorporated herein by reference in its entirety.
TECHNICAL FIELD
[0002] The present disclosure relates to the field of pharmaceutical formulations and in particular to a lurasidone hydrochloride oral soluble film composition featuring simple process and good stability, a preparation method therefor, and use thereof.
BACKGROUND
[0003] Schizophrenia is a serious mental disorder. According to the statistics of the World Health Organization, more than 21 million people are suffering from schizophrenia in the world. This disease is also the eighth leading cause of disability among the 15-44 year old. By the end of 2016, the number of schizophrenia patients registered in China was about 4.05 million. The existing drugs for schizophrenia treatment can be roughly divided into two categories. One is typical antipsychotic drugs, also known as the first-generation antipsychotic drugs, and the other is atypical antipsychotic drugs which generally have dopamine D2/5-HT2A receptor antagonism and are also known as the second-generation antipsychotic drugs. Since 2010, the market scale of mental drugs in the domestic sample hospitals has increased from 1.25 billion yuan to 2.47 billion yuan in 2015, with the 5-year compound annual growth rate reaching 14.6%. In view of the incomplete understanding of the pathogenesis of schizophrenia and the limitations in the efficacy of existing therapeutic drugs as well as the adverse effects of the therapeutic drugs, therapeutic drugs with better efficacy and less severe adverse effects are needed in clinic. The medical resources of the domestic psychiatric department are short, and the potential of the mental drug market is huge. However, in the acute phase, schizophrenic patients often refuse to take the medicine, store the medicine in the oral cavity, and spit the medicine, and the problem of medication compliance among patients is common. Thus, tablets and capsules are often ineffective for patients, and dosage forms that are easy to use are considered for schizophrenic patients. In view of the above, there is a need to provide a new formulation featuring convenient use, good compliance, and stable quality to solve the above problems.
[0004] Lurasidone hydrochloride is a novel atypical antipsychotic drug jointly developed by Takeda Pharmaceuticals and Sumitomo Pharma for treating schizophrenia, and it is used for treating schizophrenia and bipolar depression. At present, the clinical dosage form is a common tablet. However, it is difficult for the common tablet to be swallowed, and this dosage form is not suitable for children and elderly patients and cannot be taken by the patients conveniently without water.
[0005] Therefore, a dosage form of lurasidone hydrochloride needs to be developed at present to solve the problem of poor compliance of patients in taking medicines, and this dosage form should be particularly suitable for patients with dysphagia and thus can improve compliance of the patients.
